As someone with a computer heavy job and hobbies, I’m pretty impressed I’ve held onto better than 20/20 sight into my 30s. I’ve started to suspect that it might have something to do with having ADHD and the corresponding moments of distraction leading to above average amounts of eye movement and related refocusing leaving the eye “better exercised” than more attentive peers. While it’s just a data a point of one it’s always struck me as a fascinating hypothesis.

Unfortunately I’m in computers not medical research or I’d have considered proposing a study, but I look forward to the day someone else diligently studies it and I get an answer to my personal pet theory.
